I just bought a skeeter and the motor is cutting while idling, won't get any speed, just runs like a one legged duck. Any tips on where I should get started looking? Batteries are OK. Going to pop the cover tomorrow and poke around like a dummy.
Just looking for some ideas on common problems that make the old 97 Yamahas (175) cut out real bad.
Could be a simple as bad gas.
Pump the fuel bulb and make sure it holds, indicating no leaks. Then I'd start by making sure I had good spark at each of the plugs. Check the fuel filter and fuel lines really good. The Yamaha runs on very high fuel pressure and if anything is bogging it down you'll get a missing motor.
Got that handled - bad kill switch ~b~
Now the water pee hole isn't "peeing". He should have pee any time the motor's running, right? I've got the earmuffs on the lower vent holes by the prop and nothing coming out the pee hole.
Draining lower unit today and dropping it. Fingering the water pump to make sure it turns. I'll report back for anyone else that has this problem.
replace the pump, no matter what. Very cheap insurance!!
Agreed on replacing pump while your there. Some motors don't pee well until given a little gas but on muffs the hose pressure should be making its way to the pee hole. Could be a stuck thermostat as well.

My Dads Merc XR-6 wouldn't pee until the motor got up to temperature, then it was fine.
You guys know where the thermostat is on these Yamahas?
I'm a Merc guy, I would start with YouTube and search Yamaha thermostat replacement and I bet there are several how to videos

I forget Youtube is there. Wasn't around in my day haha.
I'll have a look-see. Thanks Mike
Tstat has no water (They're located up by the top spark plugs, for others interested - and there's two of them.).
Pulled the lower unit and checked out the pump. Wouldn't turn. Wonder why....

There were three rings stuck in the impeller and the impeller *seems* to be too tight to turn properly in the housing. Not sure where the rings came from but I'll be putting in a new housing this week.
Impellers are very tight. That one looks a smudge too big but may not be. Definitely shouldn't have rings floating around in it. I wonder if they are some sort of spacer that wasn't installed correctly?

Are you sure they're not thrust washers, one on top and one on the bottom?
